I'm currently running postfix in two places. I have a fully functioning postfix email server for my site's domain and at home I have postfix installed to allow my home server to send alert messages.
The home server is relaying through my home ISP's smtp server, but the messages get rejected by my site's postfix because the messages don't have a FQDN: RCPT from myhomeisp.com[xxx.xxx.xxx.xxx]: 450 4.1.8 <ian@homeserver>: Sender address rejected: Domain not found; from=<ian@homeserver> How do I tell postfix that @homeserver email's are okay despite not having a FQDN? Thanks.
